Problem with C2960 switches after upgrading the firmware on c2960-lanbasek9-mz.150-2.SE7

Hello. I have a problem with C2960 switches after upgrading the firmware on c2960-lanbasek9-mz.150-2.SE7.

 

1. On the switch WS-C2960-24PC-L lost all copper ports, optics works. after downgrading to the previous firmware versions (including c2960-lanbasek9-mz.122-50.SE5) the problem remained.

  • Trying to enable port (in log on all interfaces: *Mar  1 03:00:52: %LINK-5-CHANGED: Interface FastEthernet0/1, changed state to administratively down)

Rzn-BO(config)#int fa0/1

Rzn-BO(config-if)#no  sh

*Mar  1 03:06:55: %PLATFORM_ENV-3-LOOPBACK_PORT_POST_ERR: Fa0/1 can't be brought up because it failed POST in Loopback test.

 

 

2. On all switches with 48 ports (in particular WS-C2960+48PST-L) is a critical memory load, as a result, they are not accessible via SSH and via console, 802.1x did not work. After downgrading firmware on the switches were observed cyclic reboot. Helped firmware c2960-lanbasek9-mz.122-50.SE5.

 

What could be the problem and how to solve it?

There is nothing you can do

There is nothing you can do but RMA the appliance.  It's dead.
